Description

Technical Field

[0001] The utility model relates to the technical field of gas engine air intake filtering, in particular to a gas engine air intake filtering device. Background Art

[0002] A gas engine, usually referring to a gas turbine, is a power device that uses high-temperature and high-pressure gas generated by fuel combustion to drive the turbine and convert heat energy into mechanical energy. The working principle of a gas engine is that fuel and air are mixed and burned in the combustion chamber, and the high-temperature and high-pressure gas generated passes through the turbine, causing the turbine blades to rotate, thereby driving the operation of a generator or other mechanical equipment. Gas engines are divided into internal combustion engines and external combustion engines. An external combustion engine is one in which the heat generated by combustion converts water into high-pressure steam, and then uses steam to drive the turbine. When the gas engine is running, impurities such as dust, sand, and insects will enter the engine, so it is necessary to filter the space when the air enters the gas engine.

[0003] A multi-purpose gas turbine air intake filter device with patent application number 202022280369.6, in which the filter on the pre-filter frame is used in spring and autumn, and the filter on the post-filter frame is used in winter, and the filters can be installed on both frames at the same time, or the filters can be installed on one frame alone. Especially in special circumstances where the external environment changes, filters of different filtration grades can be installed on the pre-filter frame and the post-filter frame at the same time. In the above case, since the filter structure is fixedly connected to the main body, the filter structure will reduce the filtration quality of the air after filtering the air for a long time, and the existing gas turbine air intake filter device has low filtration accuracy, and can only filter out large particles of air impurities in the air. The remaining tiny particles will still cause damage to the gas turbine blades, thereby reducing the service life of the gas turbine blades.
